The Denver Post shares this anecdote from a Denver Nuggets practice in 2010, courtesy of fomer executive Rex Chapman:

It was the morning of a 2010 playoff game, and one of the Nuggets had just smoked some nuggets. As the team practiced, the player was so high that Rex Chapman, a team executive at the time, had to pull him aside to get him to focus.

"Across all walks of life and in every profession, people smoke (marijuana). This is no secret, and pro sports are not exempt," said Chapman, who played 12 years in the NBA. "But employers deserve and pay for A-plus employees. There is a time and place for everything. As a member of a team, guys owe it to their teammates to put their best foot forward."
